Embodiment Construction

[0026] refer to figure 1 , the embodiment of the present invention provides a range hood, including a housing 10, a fan 11 located in the housing, an air duct defined by the housing, a sensor 12 built in the air duct, and a connection with the fan 11 and the sensor 12 The controller 13. The air duct includes an air outlet seat 101 , a main cavity 102 and a smoke collecting cavity 103 . Optionally, the sensor 12 can be arranged in at least one of the following: the air outlet seat 101 , the main chamber 102 and the smoke collection chamber 103 . Optionally, the sensor 12 is a volatile organic compound sensor.

[0027] Wherein, the controller 13 includes a smoke prevention program, wherein the smoke prevention program can be selected to be turned on or off by the user, so that the selection of the working mode of the hood is more flexible. The controller 13 is configured to judge whether to start the fan according to the signal fed back by the sensor 12 when the smoke prevent...

Abstract

The embodiment of the invention discloses a range hood and a control method thereof. The range hood comprises a casing (10), a fan (11) inside the casing, an air duct defined by the casing (11), a built-in A sensor (12) in the air duct, and a controller (13) connected with the blower fan (11) and the sensor (12), it is characterized in that the range hood includes a smoke prevention program; the controller (13) It is configured to judge whether to start the fan (11) according to the signal fed back by the sensor (12). The solution can detect the smoke in time, and can intelligently distinguish the source of the smoke, so as to prompt the user to take relevant measures to keep the indoor air fresh. At the same time, it makes up for the leakage caused by the tight closure of the fire check valve or the anti-smoke treasure and the leakage caused by the loose connection of the range hood pipes in the kitchen.

Description

technical field [0001] The invention relates to the field of home appliances, in particular to a range hood and a control method thereof. Background technique [0002] In most kitchens, when the range hood is connected to the public flue of the building, there will be a problem that the oil fume from the public flue will flow back into the room. Existing solutions usually overcome this problem by connecting a fire check valve or an anti-smoke treasure in the public flue. However, there are also deficiencies in the fire check valve or the anti-smoke treasure, often causing leakage due to loose closure, resulting in serious indoor air pollution. Based on the above problems, there is no solution yet. Contents of the invention [0003] One of the technical problems to be solved by the invention is how to prevent oil fumes from being poured back into the public flue through the range hood. [0004] In order to solve the above-mentioned technical problems, the embodiment of t...
